Plot
From the earliest age, Harry Potter has gotten flashes of Lord Voldemort's memories thanks to the Horcrux inside of him. The memories, while traumatic, are in some ways both a curse and a blessing, quickly allowing him, once he goes to Hogwarts, to be hailed as a magical prodigy thanks to the Dark Lord's memories of practicing advanced spells. However, when Voldemort returns to life, Harry decides to form his own network similar to the Order of the Phoenix, which he calls the Custosæ de Lux. Adopting an older identity known by the codename of Mage, Harry soon becomes a major player in the war, someone Dumbledore considers his equal. Struggling with these two secrets, Harry has his friends to rely on, and as his power keeps growing with time, he can only win.
